There are jumpers, and then there are jumpers. And Markus Lupfer's irresistibly kooky knits fall into the latter category, thanks to their exuberant, sequinned slogans and Pop Art prints featuring lips, flamingos, ice cream sundaes, and so much more.

So naturally, we weren't at all surprised to discover that Lupfer's light-filled studio near Columbia Road Market is just as playful as the German-born designer's work. With pop music playing in the background, punctuated by bursts of colour and crystal-embellished stuffed animals at every turn, this is the sort of place where it seems impossible to have a "case of the Mondays."

Lupfer played host as we toured his wicked workspace and got to the bottom of what makes this celeb-adored designer tick. Click through to see him at work — and play, obviously.
